NTSB narrative
The pilot and passenger were returning from a local area flight. The wheel landing and landing roll were described as normal. About 1,000 feet down the runway, the right main gear collapsed, and the airplane ground looped. Postaccident examination showed that spring brackets and a bolt from the right main landing gear had fractured. Metallurgical examination revealed that all fractures were due to overload failure. The postaccident examination was unable to determine the initiating event that resulted in the overload failure and landing gear collapse.
Probable cause
The right main landing gear collapse due to the overload fracture of the hardware for reasons that could not be determined during postaccident testing and examination.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
